How to Whiten Fillings on Teeth at Home

Teeth fillings are commonly used to repair and restore the functionality of teeth affected by decay or damage. Over time, these fillings may become discolored, causing them to stand out and impact the overall appearance of your smile. If you’re looking to brighten your teeth at home and specifically target the whitening of fillings, it’s important to understand the options available and take certain precautions to ensure the best results. In this article, we’ll explore various methods and products for whitening fillings at home, providing you with useful insights and recommendations.

Understanding Teeth Fillings

Before delving into the whitening process, it’s essential to grasp the basics of teeth fillings. There are different types of fillings, including amalgam, composite resin, ceramic, and gold. Each type has its own characteristics and may react differently to whitening treatments. It’s important to be aware of the specific material used in your fillings to better understand the potential outcomes of whitening.

Reasons for Discoloration

Fillings can discolor due to various factors such as exposure to staining substances, natural wear and tear, or simply the passage of time. Understanding the reasons behind the discoloration can help you choose the most effective whitening method for your fillings.

Precautions before Attempting Teeth Whitening at Home

Before embarking on any teeth whitening journey, it is crucial to consult with your dentist. They can evaluate the condition of your fillings and provide personalized advice regarding the best approach for your situation. In some cases, it may be necessary to replace old or discolored fillings before attempting any whitening treatments.

Natural Remedies for Whitening Fillings at Home

4.1. Baking Soda and Hydrogen Peroxide Paste

One popular home remedy for whitening teeth, including fillings, is a paste made from baking soda and hydrogen peroxide. Baking soda acts as a mild abrasive, gently removing surface stains, while hydrogen peroxide has bleaching properties. By combining the two into a paste, you can create an effective homemade whitening treatment.

4.2. Lemon Juice and Salt Scrub

Lemon juice, known for its natural bleaching properties, can be combined with salt to create a scrub for your teeth. Gently massaging this mixture onto your teeth, including the fillings, can help reduce stains and brighten your smile. However, it’s important to be cautious as the acidity of lemon juice may affect the enamel if used excessively.

4.3. Coconut Oil Pulling

Oil pulling is an ancient technique that involves swishing oil in your mouth to promote oral health. Coconut oil, in particular, is known for its antimicrobial properties. While oil pulling cannot directly whiten fillings, it can help maintain overall oral hygiene and contribute to a brighter smile.

Over-the-Counter Teeth Whitening Products

If you prefer ready-to-use products specifically designed for teeth whitening, there are several options available over the counter.

5.1. Whitening Toothpaste

Whitening toothpaste contains mild abrasives that help remove surface stains, including those on fillings. Look for toothpaste with the American Dental Association (ADA) seal of approval to ensure its safety and effectiveness.

5.2. Whitening Strips

Whitening strips are thin, flexible strips coated with a peroxide-based gel. They are applied directly to the teeth, including the fillings, and left on for a specified period. Regular use can gradually whiten teeth and improve the appearance of fillings.

5.3. Whitening Gels and Trays

Whitening gels, when used with custom-fitted trays, offer a more targeted and comprehensive approach to whitening. The gel is applied to the tray, which is then placed over the teeth, allowing the gel to penetrate and whiten the fillings and natural teeth.

Best Practices for Safely Whitening Fillings at Home

When attempting to whiten fillings at home, it’s important to follow best practices to ensure safety and achieve desirable results.

6.1. Following Instructions Carefully

Whether you’re using natural remedies or over-the-counter products, always read and follow the instructions provided. This includes recommended usage times, frequency, and any precautions or warnings.

6.2. Monitoring Sensitivity

Pay attention to any signs of tooth sensitivity or gum irritation during the whitening process. If you experience discomfort, reduce the frequency or duration of treatments and consult your dentist if necessary.

6.3. Not Overusing Whitening Products

While it’s tempting to achieve faster results, overusing whitening products can lead to tooth sensitivity and damage to the fillings. Stick to the recommended usage guidelines and be patient with the whitening process.

Professional Teeth Whitening Options for Fillings

If you desire faster and more significant results, professional teeth whitening options provided by your dentist may be worth considering.

7.1. In-Office Teeth Whitening

In-office teeth whitening procedures utilize stronger bleaching agents and advanced techniques to whiten teeth, including fillings. Your dentist will take necessary precautions to protect the gums and monitor the process for optimal results.

7.2. Dentist-Prescribed At-Home Whitening Kits

Dentists can also provide customized at-home whitening kits that are stronger and more effective than over-the-counter options. These kits usually involve the use of custom-fitted trays and professional-grade whitening gels.


Whitening fillings at home can be an effective way to enhance your smile and restore the natural color of your teeth. However, it’s important to take precautions, consult with your dentist, and choose the most suitable method for your specific situation.
